If you are an RV camper, nothing should stand between you and the hot water baths after hours of tedious training. After reading the review of the top-tier products, we hope you must have gained valuable information on which products to prefer and which products to ignore. However, we understand you must be looking for a package containing tips and tricks that you can keep in mind to finalize the product.

So, there are no worries because we are here with this set of pre-purchase considerations that will help you opt for the premium quality choice. Considering our personal experience with the best tankless water heater for RV and the opinion of other RV campers, we have compiled these factors. All you have to do is keep them in consideration as you purchase the RV instant hot water heaters. Here we go with these tips and tricks!

Heating Capacity of the RV Tankless Heater

The first and most important consideration that you must keep in mind is the heating potential of the model you will purchase. You must check the item specifications for BTU. BTU is the abbreviation of the British Thermal Unit, and it will give you an idea of the heating capacity of the product you are thinking of buying. This is important to consider because while you are camping, you will notice that not all the water supplies at different locations have the same temperatures.

Some models might not work in colder climates, while others with specialized designs won’t heat the water. Therefore, you need to make a wise decision. The good news is that you can go for options that offer anti-freeze technology like:

  • GIRARD 2GWHAM Tankless Water Heater
  • Camplux Portable Propane Tankless Water Heater
  • EcoSmart ECO 11 Electric Tankless Water Heater

Also, an important thing to consider here is that sometimes you might not need very large BTUs. For example, if you need lesser BTUs, you must not go for excellent models like Rinnai RU80EN 8.0 GPM Tankless Water Heater RV offers you 157,000 BTUs. In that case, you can go for models like FOGATTI Propane Gas Tankless Hot Water Heater for RV Campers and PrecisionTemp RV-550 Tankless Water Heater.

Source of Power

Another important consideration that you must consider is the power source that your RV tankless water heater will need. Your heating unit can be operated using four modes. They are battery, propane gas, natural gas, and electric powered. Based on our personal experience, we suggest you purchase the models that run on battery or propane gas.

These two options are not only good in terms of portability but also are environmentally friendly. In this regard, you may go for propane running models like:

  • Furrion 2.4GPM Tankless RV Gas Water Heater
  • FOGATTI Propane Gas Tankless Hot Water Heater for RV Campers
  • Camplux Portable Propane Tankless Water Heater

At the same time, the best electric model that belongs in your RV is EcoSmart ECO 11 Electric Tankless Water Heater. You will be getting outstanding BTUs in natural gas, but carrying around natural gas is not recommended and is not that common in RV parks. For example, Rinnai RU80EN 8.0 GPM Tankless Water Heater RV is offering 157,000 BTUs, but you need to be very cautious about the natural gas container you take with you. Therefore, making a wise decision in this regard is very important.
